The Volume integration process combines sequential samples of a trace to create a new value. There are 2 methods available within the process:

  • Integration: This is a numerical integration method used to approximate the area under the curve.
  • Running Sum: This method adds one sample to the next, cumulatively, as it goes down the trace. For example, for an input trace where every sample = 1, the output samples will be 1, 2, 3, 4, 5, ...

Create a volume integration process

Create a volume integration process
  1. In the Control Panel, open the Process tab.
  2. At the tab header, click the Add icon and select New Process.
  3. Double-click Volume Integration.
  4. Type a name for the process and click OK.
  1. In the Details Panel, select the volume for the integration process at Volume. In this example, a density volume is selected.
  2. Select the Method for the integration process:
    • Running Sum — This method adds one sample to the next, cumulatively, as it goes down the trace. For example, for an input trace where every sample = 1, the output samples will be 1, 2, 3, 4, 5, ...
    • Integration — This is a numerical integration method used to approximate the area under the curve.

As a result of this process, a new volume is available in the Volume tab. The following examples show a density volume before and after the Volume Integration process.
